Asy sho'W-nthis box`l3emy Vbodiesa flat bottomvva'lll't' afrd'upWar'dly e shown anothermethod'of using the' device A Y oilor other liquid to drip fromthecontainer extending relatively short side wall 16. The

i upper end of the box'lS is left open andy lwhen the Ydevice A is to beused, they said Y box is filled with sand or other heavy ma#l terial toform the weight. In the drawings dep'endingstraps 16 are riveted orother-y wise secured tothe side walls of the oil container for engagingtheside walls 15 of i 'Qrmlyin place.

lthe box andthe lower ends of these. straps are provided with hooks 17for engaging the bottom wall of' saidbox fory holding the same Inaccordance wit-h the f invention7 the "supperA end of'Y the container isprovided with an oil outlet 18 of the desired size anda water inletv19in one side wall adjacent to the bottom thereof. f

" In'actual'plactice the apex of the convtainer 10 canbe closed aswellas the open- -ing19 andrthese Vplaces are marked to per mit the'desiredsized openings to be formedV therein,.when the device is to be used.-

VIntvuse of` the improved device the same is Y thrown or'pitchedinto'the waterway at an Vthe oilwill rapidly flow to the surface ofadvantageous *point and it canbe seenthat Y j thestreamfor waterwayV andcover.l the surfacefthereof and thus preventk the breeding ofV themosquitoes.

I n Figure 4 of the drawings, I have and in thisrnethod the weight canbe disi Vpensed 'with Vand the, bottom wall of the container isprovidedwith a 'pivoted eye 2O `whichjis adapted to receiveA a hook 21 formedonan arm 22. irllhis arm 22fis formed on or carried by a suitable post23 and by this construction fitv `canbe seen'that the container A isheld in an elevated position with the apex thereof lowermost which'allows the on tthe surface of the water. `VItis preferred however to usethe container as the sub- Y mersiontypaas such results can be obtainedfrom Vsuch use', but I have lshown in Figure 4; the method vof using thecontainer by al lowing ythe oil to 'drip therefrom, so that thecontainer can be used under all conditionsfsuch aslin low marshyland. V

f In Figure 5 of the drawings I have shown Still another method ofusing' the device and this method can Ab,e"employed when the.

` waterway Yis of'adeep character.

In this method the weight 12 is employed and'` afsuitable .rope or cable25 is tied to thev strop Vor shackle. 1l and then to a suitablel y float'26, which can bea dead log or the like 'as shown in .the drawings.

In `Figures' and 7 ,I have shown aislightly modified formY of' theinvention which is generally indicated by the ,reference char-'acterrltV In this form I also provide a pyramidal' shaped container 30,the apex portion of which isLprovided with an'outlet spoutel which canbethreaded for there- Qception ofV a cap or the like As shown the cap32-is provided with a carryingringV 33. The container 30 adjacent to thelower end thereofv is provided withV a iillingspout or the like 34 bymeans of which the oil or other-.liquid can be poured intothe containerandthis spout is closed by a cap 35. When the device is in use thel capsV32 and 35 can be'removed in order to allowl the exit of the oil orother liquid and the entrance of water into the same to displace theoil.A y

Invorder to hold the container submerged in the body of water andin anupright position, a partition 3G is placed in the containery adjacent tothe lower end thereof defining a compartmentv 37 which can beV filledwith a suitable material yof a heavy character, Vsuch afs sand or thelike.

ofthe container 30 is also provided. with a filling spout 38 whichlcommunicates with the compartment 3 7 and permits the intro-k Y ductionof sand or other heavy material into the same.` Thisspout is also closedby a suitable cap 39. Thebottomwall of the container canalso be providedwith asuit-` tion of the device.

If desired the partition 36 can beprovided f with a central group ofopenings il so as to allow communication to be had between the Thebottom wall 'j body of the container and the compartment 37. In FigureSvof the drawings, I have shown another slightly modified form of theinvention in which a wick 50 can be utilized for dispensing oil from thecontainer to the.

water. As shown the wick 50 extends through a suitable opening 51 formedat the apex of the container 52 which can be of the same type as thecontainers shown in the previous form.

' v 105 From the foregoing description, it can bev seen that I haveprovidedV a novel means forA supplying oil or other'liquid by the'submersion method to a waterway for effectively preventing the breedingof mosquitoes.

Changes in details may be made without departing from the spirit or lthescope of,

this invention, but:

lVhat I claim as new is :f Y1. A device'lor preventing the breeding ofmosquitoes, a liquid receiving Ycontainer gradually converging towardone end and end and means for associating a weight with the face of thecontainer' including a com-KV provided with a liquid outlet opening atsaid Y' 9o y Vable eye 40 for kfacilitating 'thev manipula@ 3. In adevice for supplying oil and other anti-mosquito breeding liquid toWaterways by the submersion method, a container grad-V terial detachablyassociated with the end ofl the container remote from the outlet endthereof, and handles associated Wtith the idalsha'ped container havingan outlet opening 1n the upper end thereof and a Water inlet openingadjacent tothe' opposite end thereof, means for closing the openingswhen v Y' the container is not in use, a partition disposed Within thecontainer adjacent to the base granulated material receivingcompartment, means for filling the last mentioned compartment With heavymaterial, and manipulating handles associated with the container. I

In testimony whereof I aiix my signature.
